Malkit Singh, in Waste and Supplementary Cementitious Materials in Concrete, 2018. Costbenefit analysis. Worldwide, utilization of coal ash (mixture of FA and CBA) was 360 Mt against 780 Mt of production in 2010. The statistics shows that major portion of coal ash utilized is FA and remaining unutilized part of coal ash is disposed off in ash ponds.

One of the reasons fly ash is so popular as an additive, of course, is that there''s a lot of it left behind by coal plants. At the same time, one big point in favor of fly ashs use in concrete and brick is the idea that a chemical reaction is believed to effectively trap any minute levels of fly ash
